Understanding the TOSCA Type System: Node, Relationship, Requirement, and Capability Types
This presentation outlines the TOSCA type system, categorizing types into Base Types, Specific Types, and Custom Types. Base Types establish the fundamental structure of the TOSCA type system and serve as a foundation for future extensions, while Specific Types cater to particular solutions like infrastructure or middleware. Custom Types can be developed for point solutions. Concrete examples include Node Types from the SugarCRM model, demonstrating how types like "NetworkEndpointCapability" and "NetworkEndpointRequirement" combine essential requirements and capabilities. Join the discussion on necessary inheritance levels.

Presentation Transcript
Objective • This presentation outlines a type system for TOSCA Node-, Relationship-, Requirement- and Capability Types • Types are categorized into • Base Types: define the base structure of the TOSCA type system, independent of any specific solutions; base types should be the anchor point for future extensions • Specific Types: define types for specific solutions, like specific infrastructure, middleware or application content; specific types are derived from base types • Custom Types: define custom types for point solutions, like very specific applications, or customized solutions; custom types typically are derived from specific types
NodeTypes used in simple SugarCRM model Concrete Node Types used in SugarCRM example
Endpoint Requirements & Capabilities Combine into one type “NetworkEndpointCapability” Combine into one type “NetworkEndpointRequirement”
For discussion What level of inheritance are necessary?
